Kendall was playing t-ball and hit the ball off the tee, which is 3 feet off of the ground. If the equation h(t) = -16t2 + 20t + 3 represents the height of the ball at time t, what would the x-intercept represent in the context of this problem? Write your answer using complete sentences.

the x-intercept would be the time taken to hit the ground
Hmmm. I see h(t), but no x.
I expect you meant to ask what the t-intercept means. Reiny's answer would be the one you want.
Generally in problems like this, x represents the distance traveled horizontally. So, in that case, the x-intercept wold be how far away the ball hit the ground.
